To the orient, I would take Northwest. They have had over 50 years of experience in the orient. Although I would consider Cathay Pacific also. Depends on the fare.
i personally like CX, so i try to fly them wherever i go....but i dun mind flying SQ and JAL....cos from my experience...they are also very good.....you know, when you are enjoying the flight.....the little extra flying time won't be such an issue!!!!! you may even want to stay in the air longer!!!!!
